Remote asymmetric induction by the vinylogous Mukaiyama aldol reaction using the acetate-type vinylketene silyl N,O-acetal possessing a chiral auxiliary has been achieved. The silyl N,O-acetal derived from crotonate and L-valine afforded the O-silylated 5R- and 5S-adducts selectively by treatment with SnCl4 and BF3·OEt2, respectively. The SnCl4-mediated isomerization of silyl dienol ether was found, and the resulting major isomer showed high reactivity to give gamma-adduct in high stereoselectivity.

Electric Literature of 160695-26-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 160695-26-1, (R)-4-Phenyl-3-propionyloxazolidin-2-one, introducing its new discovery.

(Matrix Presented) The highly stereoselective synthesis of beta-amino acids via the chiral 4-phenyloxazolidinone-controlled linear N-acyliminium ion reaction has been achieved by employing chiral N,O-acetal TMS ethers. In addition, the mechanism of the excellent stereochemical outcome has been elucidated. The oxazolidinone auxiliary plays a dual role in stereocontrol: the E/Z geometry control of the N-acyliminium ion induced by an initial stereoselective amide reduction, leading to the chiral N,O-acetal TMS ether, and face control of the nucleophile attack in the N-acyliminium ion reaction.

Helicobacter pylori is a Gram-negative bacterium that colonizes the gut of over 50% of the worlds population. It is responsible for most peptic ulcers and is an important risk factor for gastric cancer. Antibiotic treatment for H. pylori infections is challenging as drug resistance has developed to antibiotics with traditional mechanisms of action. H. pylori uses an unusual pathway for menaquinone biosynthesis with 5?-methylthioadenosine/S-adenosylhomocysteine nucleosidase (MTAN) catalyzing an essential step. We validated MTAN as a target with a transition-state analogue of the enzyme [Wang, S.; Haapalainen, A. M.; Yan, F.; et al. Biochemistry 2012, 51, 6892-6894]. MTAN inhibitors will only be useful drug candidates if they can both include tight binding to the MTAN target and have the ability to penetrate the complex cell membrane found in Gram-negative H. pylori. Here we explore structural scaffolds for MTAN inhibition and for growth inhibition of cultured H. pylori. Sixteen analogues reported here are transition-state analogues of H. pylori MTAN with dissociation constants of 50 pM or below. Ten of these prevent growth of the H. pylori with IC90 values below 0.01 mug/mL. These remarkable compounds meet the criteria for potent inhibition and cell penetration. As a consequence, 10 new H. pylori antibiotic candidates are identified, all of which prevent H. pylori growth at concentrations 16-2000-fold lower than the five antibiotics, amoxicillin, metronidazole, levofloxacin, tetracyclin, and clarithromycin, commonly used to treat H. pylori infections. X-ray crystal structures of MTAN cocrystallized with several inhibitors show them to bind in the active site making interactions consistent with transition-state analogues.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C11H21NO4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 108149-65-1, in my other articles.

Purpose: To develop block copolymer micelles as an aqueous dosage form for a potent glycolytic enzyme inhibitor, 3-(3- pyridinyl)-1-(4-pyridinyl)-2-propen- 1-one (3PO). Methods: The micelles were prepared from poly(ethylene glycol)-poly(aspartate hydrazide) [PEG-p(HYD)] block copolymers to which 3PO was conjugated through an acid-labile hydrazone bond. The optimal micelle formulation was determined following the screening of block copolymer library modified with various aromatic and aliphatic pendant groups. Both physical drug entrapment and chemical drug conjugation methods were tested to maximize 3PO loading in the micelles during the screening. Results: Particulate characterization showed that the PEG-p (HYD) block copolymers conjugated with 3PO (2.08?2.21 wt. %) appeared the optimal polymer micelles. Block copolymer compositions greatly affected the micelle size, which was 38 nm and 259 nm when 5 kDa and 12 kDa PEG chains were used, respectively. 3PO release from the micelles was accelerated at pH 5.0, potentiating effective drug release in acidic tumor environments. The micelles retained biological activity of 3PO, inhibiting various cancer cells (Jurkat, He-La and LLC) in concentration ranges similar to free 3PO. Conclusion: A novel micelle formulation for controlled delivery of 3PO was successfully prepared. Springer Science+Business Media, LLC 2011.

Herein we report the first total synthesis of the natural product Urkuthaplestatin A (Ustat A) utilizing a convergent synthetic strategy. The characterization and biological activity match those of the previously published natural product. Interestingly, several intermediates, including the linear and serine cyclized precursors, show a 100-fold decrease in cytotoxicity, with IC50’s in the low micromolar range. These data indicate that the rigidity and the consecutive aromatic heterocyclic system are responsible for the biological activity.

General enantioselective routes to 3,4-cis-dialkyl substituted gamma-lactones and 4,5-cis-dialkyl substituted delta-lactones using TiCl(4)-mediated Evans asymmetric aldolization as the key step are reported. The syntheses are exemplified with two natural fragrant molecules, cis-3-methyl-4-decanolide (1) and aerangis lactone (2). The (R,R) steroegenic centers were established using (S)-phenylalanine-derived 2-oxazolidinone or thiazolidinethione as chiral auxiliary, whereas the (S,S) ones were constructed with auxiliary prepared from (R)-phenylglycine. NaBH(4)/CaCl(2)/THF in the presence of a small amount of EtOH was introduced as a new effective method for reductive cleavage of chiral oxazolidinone auxiliaries. Previously unknown, tricky concentration effects were observed during the monotosylation of diol 7 and BOM protection of Evans aldol 23.
